Specification of Letters` Patent. i PatntdfJuly 8, 1919.

Application led April 13, 1918. Serial No. 228,404.

To all/whom t may concern:

Be it known that I, FURNEY F. GREEN, a citizen of the United States, residing at Coalgate, in the county of Coal and State of Oklahoma, have invented a new and useful Tire, of which the following is a specification.

The device forming the subject matter of this application is a tire and one object of the invention is to provide novel means whereby the creeping with respect to the rim. Another object of the invention is to provide novel means for limiting the movement of the tire with respect to the rim. It is within the province of the disclosure to improve generally of that kind to which the invention appertains. Changes such as a mechanic might make, may be resorted to, within the scope of what is claimed, without departing from the spirit of the invention.

In the drawings Figure 1 shows in side elevation, a device constructed in accordance with the invention, parts being broken away; Fig. 2 is a cross section on theline 2-2 of Fig. 1; Fig. 3 is a section on the line 3-3 of Fig. 1; Fig. 4 is a section on the line 4-4 of Fig. 1'; Fig. 5 is a perspective showing a portionof the support; Fig. 6 is a section corresponding to Fig. 3 but showing a modification.

In carrying out the invention, there is provided a rim l including a base 2 and side flanges 3. Disposed between the flanges 3 are inverted trough-shaped supports 4, there being preferably four of these supports, arranged end to end about the rim. Each support includes a tread portion 5 and side iianges 6, the edges of the flanges being formed into troughs 7, each comprising a base 8 and a side flange 9. The bases 8 rest upon the base 2 of the rim l, the side flanges 9 co'perating with the flanges 3 of the rim 1. Between the ends of the support 4, the troughs 7 are cut away as shown -at 10 to form openings 11. Rubber buffer strips are seated in the troughs 7, the strips being shown at 12. Openings 14 are formed in the side flanges 6 of the support 4.

The numeral 15 denotes a metal tire which may have some resiliency. The tire comprises a body 16 and parallel wings 17 received between the parts 6 of the support 4 and the parts 3 of the rim 1. Transverse corrugations 18 are formed on the wings 17 tire will be prevented fromv and to enhance the utility o-f devicesV of the tire 15 and are extended upon the body 16 of the tire. Thecorrugations 18 strengthen the tire and serve to take up the metal when the tire is bent into circular form. Reinforcing rings 19 are secured to Y the outer surfaces of the wings 17v of the tire 15, preferably by spot'-welding. The ends of connecting devices v20 are mounted in the rings 19 and pass through the wings 17 of the tire 15. The connecting devices 20 move in the openings 14 of the support 4. The tread portion of the tire body 16 is provided with a depressed seat'21 the bas-e of which is supplied with transverse corrugations 22. A tread 23, preferably made of rubber, is mounted in the seat 21 and cooperates with the corrugations 22, to avoid creeping. The tread 23 may be provided with reinforcing wires 24.l

A cushion 25 preferably in the form of a pneumatic tube is located in the body 16 of the tire 15 and tube 25, the shoe resting on the par't 5 of the support 4, the cushion carrying an inflating tube 26 extended through the part 5 of the support 4 and through the base 2 of the rim 1. The cushion 25 supports the tire 15 yieldingly but when the cushion gives to a sufficient extent, the edges of the rings 19 and the wings 17 of the tire come into contact with the buffer strips 12 in the troughs 7.

Thereinforcing rings 19 are provided on their outer sides with undercut recesses 27 which are oppositely disposed, there being ordinarily but one pair of these recesses. Plates 28 are disposed in the' recesses 27 and have beveled ends 29 coperating with the undercut ends of the recesses, the plates being held in place by securing elements 30 engaging the rings 19. Undercut recesses 31 are formed in the plates 28, and undercut recesses 32 are formed in the side flanges 3 of the rim 1. Strips 33 are provided, lthe same having notches 34 in their extremities, the notches forming beveled parts 35 and beveled parts 36 at the ends of the strips. The beveled parts 35 coact with the undercut ends of the recesses 32 in the side flanges 3, the beveled parts 36 being slidably received in the undercut recesses 31 of the plates 28 as clearly disclosed in Fig. 3. The strips 33 are secured to the side Hanges of the rim 1 by securing elements 37. The parts above described, and shown in Fig. 3 prevent the tire 15 from creeping on the rim 1. The

a shoe 76 coperates with theplates 33 extend into the openings l1 in the troughs 7.

The side fianges 3 of the rim lare struek outwardly at intervals as shown at 38 to form internal seats 39 in which are mountedV wear plates 40 held in place by securing elements 4l. Recesses -42 are formed in1 the rings 19 and wear plates 43 are held in the` nated by numerals, already used, with the suffix a In this form of the:y inventiom the strip 33a has 4thinned ends 46vreceived in depressions 47 in the ring 19u.

I claim z* l; Ina device of the class described, .a rim comprising a base. and side flanges; an inverted trough-shaped support located between the side flanges of the rim land including a tread and side flanges, the edges of the side flanges oft-he support being fashioned into' troughs including bases resting on the base of the rim, andside flanges coperating with the side flanges ofthe rim; buffer strips seated in Ithe troughs; a tire including vwings slidable between the side flanges kof the lrirn and the sideV fiang'es of the support and alined with thefbufler strips; and a cushion interposed between. the support and the tread portion ofthe tire, the wings of the tire coacting with the buffer strips whenthe cushion yields@ 2. In a` device of k,the class described, airini comprising av base, andside flanges provided with terminally undercut recesses; a tire including wings received slidably between the fianges o-f-l the rim; reinforcing rings secured to the wings of the tire and having terminally undercut recesses; plates fitting in the recesses of the rings and secured therein, the plates having beveled portions coperating with the undercut ends of the recesses in the rings, the plates having terminally undercut recesses; strips having notches in their endsv defining sets of oppositelyvv beveled parte, engaging the -undercutiends of the recesses in -theside flanges of the rim, and the parts ofthe other set, coperating sli'dably wit-h the undercut ends of the recesses in the plates; -means for securingthe strips to the side flanges of the rim; and means for supporting "the tirer yieldingly with'respect to the` rim.

3; In :a device of the class described, a rim comprising/a,base and sideflanges; a tire in` cluding, a body., .and `wimgsreceived slidably between theA side flangesvof the rim, the wings. having transverse corrugations eX- tended upon theAL sideY portions of the. body ofV the 'tire vand i terminated in spaced i relation tothe tread of the tire; and means-for support-ing, thetire yieldingly withk respect to the rim.'y v

In testimony that/,I claim the foregoing ,as my own, I. have hereto affixed: my `signature in thepresence of two witnesses.
